Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed May 12, 1916. Serial No. 97,085.

To all whom t may concern.'

Be it known that I, LEON J. VEATHER- WAX, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Heating-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements 1n heating stoves and furnaces, particularly of the type designed to burn soft coal, and which has a magazine for holding a large amount of fuel above the lire box, one object of the invention being to prevent the fuel within the magazine from becoming prematurely ignited before entering the fire boX.

Another object of the invention is to admit of air being admitted directly below the lower end of the magazine and above the center of the fire box, so as to effect perfect combustion andA prevent smoking of the fuel.

A further object of the invention is to provide a novel type of magazine, capable of having vertical adjustment, with respect to the ire box, so as to admit of the amount of fuel to be consumed at one time being regulated.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming a part thereof, in which:

Figure 1 is a vertical sectional view, taken through the heating stove.

Fig. 2 is a transverse sectlon, taken on the line 2-2 of Fig. 1.

Fig. 3 is a vertical sectional view, taken through the magazine, showing the same detached from the stove.

Fig. 4 is a transverse section, taken through the magazine.

Fig. 5 is a detail sectional view of the base of the heater illustrating the arrangement of the lower passages. U

Referring to Fig. 1 of the drawings a heating stove is shown and is designated by the letter A, as an entirety. The stove is provided with the usual fire box 1, and ash pit 2, the latter having a receptacle 3 therein for the collection of ashes which drop from the iire box 1. The stove has a lower flue 4 therein, which has its rear end communicating with the lower end of a vertical flue 5, the upper end of the flue 5 communicating in turn with a flue (5 designed to communicate with the Chimney, not shown. The lower flue 4: is formed by a partition plate 7 which is disposed above the lower end wall of the stove casing and the -said plate 7 is disposed in spaced relation with the under side of the lower wall of the ash pit so as to provide another flue 8. The forward end of the plate 7 is spaced from the front wall of the casing to provide a passage 8 that establishes communication between the respective flues l and 8. The plate 7 is provided with a longitudinally extending flue 9, consisting of a rectangular pipe connected at the median line of its side walls with the partition 7 having its top and bottom walls lying above and below the plane of the said partition 7 The front end of the said reetangularlue or pipe communicates with a suitable draft opening formed in the lower portion of the front of the stove casing and controlled by a suitable damper 10. The rear end of the said rectangular pipe or flue is connected to and communicates with forwardly converging arms or .terminals 1la of vertical pipes 11 (see Fig.

2) which pipes 1l have their' upper ends extended inwardly and through the side wall of an air chamber 12, located at the upper end of the stove casing.

The stove magazine is designated by the numeral 13, as an entirety, and includes a stationary upper section lll and a lower section 15, which lower section 15 is mounted for vertical adjustment on the lower end of the upper section 14. A casing 16 encircles the major portion of the section 15 and is spaced therefrom and is secured to the section 15 4by means of the spacing bolts 17. The upper ends of the section 15 and the casing 16 extends through the lower wall of the air chamber 12 and the lower end of the casing 1G extends beyond the lower end of the section 15 and is deflected inwardly to provide a delector or baille 1S, which overlies the center of the fire box 1. IVhen the magazine 13 is .filled with fuel, and the damper 10 is in an open position, air will be admitted to the pipe 9 and will be drawn upwardly through the pipes 11 into the interior of the air chamber 12 and the air is then drawn downwardly from the air chamber 12 through the space between the lower section 15v and the casing 16 so as to effect cooling of the magazine and prevent premature ignition of the fuel therein, the air then passing out through the lower end of the magazine and deiected by the baffie 18 toward the center of the fire box 1 to assist in the combustion of the fuel therein. By virtue of having the lower section 15 of the magazine adjustable, the amount of fuel to be burned at one time can be regulated. The sliding of the lower section 15 is effected by means of an operating lever 19, which has one end connected to one end of a yoke 20, the arms of the yoke straddling the casing 14 and being secured thereto in any suitable manner. The lever 19 is 'pivoted to' a depending bracket 21, carried by the lower wall of the air chamber 12, and the said lever passes through a slot 22 formed in the adjacent side wall of the stove casing, and through an opening formed in a slidable plate 23, which is designed to cover the slot 22, the outer end of the lever having connection with an -operating handle 24 by means 4of which the lever 19 can 'be raised and lowered to effect sliding of the lower section 15 of the magazine. The handle 24 is adapted to be held in adjusted position by means of the segmental rack 25, which is carried by the stove and a locking pawl 26 carried by the handle.

The Hue 8 has communication with the fire box, by means of a vertical flue 27, which has its upper end opened and disposed above the upper end of the fire box 1.

When the damper 10 is opened air is admitted to the pipe 9 and is drawn through the pipe 11 to the air chamber 12. The air then passes downwardly from the air chamber 12 through the space between the section 15 and the casing 16 of the magazine and is deflected toward the center of the fire box. The heated air is then drawn from the fire box downwardly through the liue 27 to the flue 8 and thence over the pipe 9 so as to heat the air passing through the pipe 9, and thence into the flue 4 and passed through the flue 5 to the chimney, not shown.

Having thus described my invention what I claim as new, is:

l. In a heater of the character described, a casing having an air chamber therein located at the upper end thereof, a fuel magazine located within the casing and including a lower slidable section, the said magazine having the upper end thereof extending into the air chamber, a cylindrical wall encircling the slidable section in spaced rethe upper end thereof, a fuel magazine lo-- cated within the casing and including a lower slidable section, said section having the upper end thereof extending into the air chamber, a cylindrical wall encircling the slidable section in spaced relation thereto and having its upper end slidably extending into the air chamber, said wall having the lower end thereof terminally extending kbelow the lower end of the slidable section of the magazine and deiected inwardly,

a lever pivotally secured intermediate its ends to the casing, saidl rod having its inner end forked and pivotally secured to the sliding section of the magazine, and means carried by the free end of the lever for engaging the outer surface of the casing to hold the same against movement, as and for the purpose specified. i

3. A heating structure comprising a casing, a fire box in said casing, a magazine arranged above said fire box, a partition arranged' between the magazine and the casing and the upper wall of the casing, a lower partition plate mounted in the lower end of the casing, and dividing the lower end into a pair of superposed flues, said second partition plate having front end thereof spaced from the wall of the casing to provide a passage for establishing communication between the superposed fiues, an air inlet pipe located beneath the fire box and carried by the lower partition, a pair of branch pipes connected to the rear end of and extending upwardly from said air inlet pipe to the upper portion of said casing and into the chamber formed by the first partition wall, means for establishing communication between the chamber formed by the rst partition and fire box, and a flue communicating the fire box with the uppermost ue of the superposed pair of flues, as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

LEON J. WEATHERWAX.
